Chapter 5
Section 4

- comparing primitive data types
  - comparing the contents of variables
  - variable contents are actual values
- ways to compare objects
  - variable contents are addresses
  - == only returns true if the two variables point to the same object
  - define comparison methods for a class
    - many standard classes already do this
      - e.g. String
        - equals: true if the two Strings have the same characters in the same position
        - equalsIgnoreCase: true if the two Strings have the same characters (ignoring case differences) in the same position

Quick Check
